What is the ABA routing number?

The ABA routing number is a 9–digit number assigned to financial institutions by The American Bankers Association (ABA) to identify the financial institution from which a payment was drawn. Routing numbers are sometimes referred to as “check routing numbers”, “ABA numbers”, or “routing transit numbers” (RTN). Routing numbers may differ depending on where your account was opened and the type of transaction made.
